[5] On the 1997 British Lions tour to South Africa, Robson was involved with the immediate care of Will Greenwood when he sustained an injury that left him unconscious.
[12] On the 2009 Lions tour to South Africa, he had needed to comment about the number of players who had received treatment in hospital after the second test.
[13] At the end of the test he expressed concern around the number of injuries and concussions sustained by players- he advised that to protect players changes should be made on future tours, such as matches being spaced further apart.
[14] Robson was on duty with the Scotland team at the Millennium Stadium in 2010 when Thom Evans suffered serious injury and he attended to the player on the pitch.
[10] After leading research in concussion injuries and raising awareness of them,[16][17][18] by 2015 Robson was also calling for review of the way that rugby was played and the rules around the sport.
[21] Later that year, the findings of research were published and indicated that former international rugby players faced a significantly increased risk of neurodegenerative diseases compared to the general population.
